Why It May Be Okay to Sit
We've all heard the warnings. Long hours of sitting everyday increases our risk for just about every disease known to man. But wait. Just how much sitting time is bad for our health? When it comes to heart disease risk, it turns out that the magic number is about 10 hours a day.
Nine long-term studies involving about 700,000 adults looked at average daily inactivity—periods of sitting, watching television, driving, etc.—and incidence of stroke and heart attack. When researchers analyzed this data, they found that sitting fewer than 10 hours a day is unlikely to increase heart disease risk.
Before you settle in at your desk or plop down in that easy chair, research does show that—compared to sitting less than 3 hours each day while awake—being sedentary for more than 10 hours a day increases the risk for heart attack and stroke by about 8%, and sitting longer than 12 hours a day is associated with a 14% higher risk for a cardiovascular event. Staying active and eating a healthy diet are still proven ways to reduce your risk for heart disease.
